Hello, I have a flashed cMP 4,1 to 5,1 and I recently bought an SM951 together with the LYCOM PCI adapter. OSX works perfectly, but my bootcamp WIN7 OS stopped working right when I installed the SM951 (in the 3rd PCI slot). Since then i've tried both BIOS and EFI installs, with OSX 10.7.5 and 10.9.5, flashed Radeon card and default GT120 original cMP card, ssd's hard disks, full disk partitioned disk, you name it. Also tried with WIN 8.1. Soon as I install the SM951 blade anything windows stops working. That includes installation cd's, usb's HDD's ssd's, etc. Any help is appreciated.
